“Geography can be tough. Here’s a guide for Russian soldiers who keep getting lost & ‘accidentally’ entering Ukraine,” the delegation’s Twitter account said, with a picture of a map marked “Russia” in red and “Not Russia” in blue.

The tweet came after Kyiv released interrogation videos Tuesday of Russian paratroopers, which Ukraine said were on a special mission to back separatists within their territory.

Russia claimed its soldiers were lost when they crossed the border, which Ukraine firmly denied.

“This wasn’t a mistake, but a special mission they were carrying out,” Ukrainian military spokesman Andriy Lysenko said.

The Canadian tweet came after a rousing speech on Tuesday in which Prime Minister Stephen Harper promised that Canada would be ready for any Russian incursions in the Arctic.

“In Europe, we see the imperial ambitions of Vladimir Putin, who seems determined that, for Russia’s neighbours, there shall be no peace…,” Harper told Canadian soldiers in a tough speech in the North Tuesday.

“And because Russia is also Canada’s neighbour, we must not be complacent here at home.”
